Suppose you took the top 10 live cash pros and the top 10 online cash pros in the world. Let's not debate who they are, but assume there is a reasonable particular benchmark for assigning who the top players actually are. Let's assume their best game is NLHE and that NLHE is the game of choice for this question. Let's say you analyzed the most recent 100,000 hands of each and every one of these individual pros (and let's just exclude those hands where these pros happened to have played any of the other top pros in these particular hands). You looked at every one of these hands, whether they limped, raised, 3-bet, folded, won, or lost - so long as they made it to the river; they could have folded by the river, so long as they got there.
First question: what percent of these hands do you think they - collectively, as a group of players - were bluffing (let's include semi-bluffs)?
Second question: do you think there are noticeable differences between the percent of time that the live cash pros were bluffing versus the percent of time that the online cash pros were bluffing?
